13 Claims. 1

The present invention pertains to an improved, manually operated apparatus for assembling end reinforcing rings to the bodies of cylindrical paperboard containers such as are commonly employed in the shipment of bulk ice cream. The operations performed by the present apparatus include the application of one end of the container wall, previously expanded to cylindrical shape from its original flat, knocked-down condition, of a relatively rigid, pro-shaped metal reinforcing ring or bead, and the assembly to the opposite end of the container of a fiat bottom disk closing that end, together with a meeting ring, generally similar to the first mentioned ring, which reinforces the container and holds the end closure disk against outward displacement.

It is an object of the present invention to provide a relatively simple, inexpensive and readily operated apparatus which is particularly well adapted to perform the foregoing operations, and thus make it possible to assemble two reinforcing rings and a bottom closure disk to the cylindrical body of the container as a rapid, single procedure performed by a single operator.

Another more specific object of the present invention is to provide a device or apparatus of the foregoing character, including a pair of contractile members adapted respectively to engage and hold the top and bottom reinforcing rings whichare to be applied to the container, which members are mounted on pivotally connected supports movable relative to one another to enable shifting of the members to and from operating position, and mechanism operatively connecting these members in a fashion to apply the reinforcing rings to the cylindrical container body as a single, manually controlled operation.

Astill further object of the invention is to provide an apparatus capable of being rapidly and easily operated by a single workman and performing automatically all of the manipulations necessary to set up a cylindrical, reinforced container body, including the simultaneous engagement of a pair of relatively rigid reinforcing rings which are to be applied to the top and bottom of the cylindrical container body by contractile assembling members, the applicationof said rings to the body, together, if desired, with an end closure disk which is held in fixed relation to the body by one of said rings, by relative 'movement of the assembling members into operating position with respect to the container body ends, and the release of one of the contractile members to permitrelative' retraction of the assembling members from said position, which apparatus performs the necessary operations at both ends of the container body Without damage to the container parts and with uniformly successful results.

More specifically it is an object of the invention to provide a container assembling apparatus characterized by a pair of contractile split assembling bells, each including a pair of pivotally connected sections of semicircular shape, said respective bells being movable relative to one another, and each being contractible to engage the relatively rigid reinforcing rings which are intended to be assembled to opposite ends of the container body; by individual actuating devices or mechanisms to contract said respective bells in proper relation to the rings for the assembly; by manually operable means operatively connected to said bell actuating devices or mechanisms for simultaneous or coordinated, automatic operation; and by means to automatically release at least one of the bells from contracted, ring engaging position practically instantaneously following the assembling operation, thereby permitting reverse movement from assembling position.

A still further object is to provide such an apparatus which has adjustable provisions enabling a given apparatus to be employed in assembling cylindrical containers of different axial lengths.

The foregoing statements are indicative in a general way of the nature of the invention, but other and more specific objects will be apparent to those skilled in the art upon a full understanding of the construction and operation of the device.

A single embodiment of the invention is presented herein for purpose of illustration, but it will be appreciated that the invention is susceptible of incorporation in other modified forms coming equally within the scope of the appended claims.

Referring particularly to Figs. 1, 4 and '5 of the drawings, the apparatus disclosed therein is composed of the following main components: A

"suitable rigid supporting base ll! on which is mounted a mandrel assembly I l, a ring clamping assembly l2, a supporting head l3 'pivotally mounted on base II], a ringclamping assembly 14 on the head and a linkage generally designated l5, which is actuated by a foot pedal is and has the function of automatically and conjointly actuating the mandrel and clamp ring assembly I I, I2 on base Ill and the head clamping assembly 13.

The base In comprises a horizontal plate-like supporting table l8 which is sustained by any suitable provision, illustrated in the present apparatus as a depending, rigid, shaped sheet metal skirt I9 which functions furthe'r'as a shield and closure for certain'operating parts of the apparatus. A pair of tubular posts fitted into vertical apertures adjacent the rear of the table 18 supplement the supporting action of the skirt l9. The front, rounded surface of the skirt-like table I9 is provided with-a vertically elongated, laterally stepped aperture 21 through which the pedal [6 projects.

Reference should be made to Figs. 4, 5, '7, 8 and 9 in connection with the mandrel assembly H on table l8. lit-comprises a split, "expansible and contractible hell or ring 22 made up of a pair 4 of relatively deep, semicircular externally ribbed cast sections 23 of like shape which are pivoted to one another. Each of the castings 23 is of gradual, inwardly and downwardly curved contour on its inner surface 24, said surface terminating at its lower extremity in a shaped annular undercut recess 25 which is adapted to receive one of the metal reinforcing rings to be applied to the container, as hereinafter described. Bell sections 23 are provided with a radially outwardly extending, continuous flange 26 which slides on the table l8 in the inward contractile and outward expansive pivoting movement of sections 23 in the operation of the ring clamping bell 22.

The bell sections 23 are pivoted to one another by means of a vertically extending pin 21 on the table l8 extending through pivot ears or bosses 28 located at the rear of the sections. A vertically extending pivot bracket 29 is secured to the table and is provided with a forwardly extending boss 30 which receives the upper extremity of the pivot pin '21. A c'oil compression spring 3| disposed in outwardly bored recesses in the bell sections 23 adjacent the pivot pin 21 (see Figs. '7 and 8) serves to urge said sections away from one another to'the open position illustrated in Figs. '7 and '8.

Each of said sections 23 carries a rigid post 32 located somewhat forwardly and outwardly of the rear pivoted end thereof, which posts 32 extend downwardly through inclined slots 33 in the table l8. These posts-32 are adapted to connect the bell sections 23 with the automatic actuating provisions of the apparatus, hereinafter described in detail.

Referring to Figs. 5 and 9, the table I8 is provided with a central, downwardly extending boss 34 which is bored at 35 to slidably receive the tubular, vertically reciprocabl'e, actuating plunger 36. The latter is shaped at its upper extremity to provide a conical cam 31 slidably engageable with a plurality of radially shiftable mandrel cone segments 33, each provided with small, undercut ring receiving recess on the lower edge of its outer arcuate periphery. I'he segments-38 are provided with grooves opening to the bottom surface thereof in which the annular segmentcontracting garter spring -39 is disposed. They also are provided with radially disposed slots 40 which open at their upper end to the circumferentially extending grooves 4! of substantial size in the "upper surface of the segments. Four equi-spaced pins 42 are threadedly secured to the able I8 to extend upwardly through slots 40 and groove -4l, being surrounded by the small guide sleeve 43 in theslot. These pins guide the segments 38 in their radial outward sliding "movement under the influence of the cam 31. A mandrel rocker supporting "ring 44 disposed in groove 4| atop the segments 38 is held in nonrotative relation'to the table l8 by means of the pins 42, which-extend through radial ears on the supporting ring '44. Said ring serves as a rocking support for the "drum-like mandrel 45 which, as illustrated iniFig. 9 has a base spider 45' provided with a slightly rounded ar'cuate rocker surface resting on ring '44. Thus limited front to rear rocking of the mandrel is permitted when the assembling head I4 is thrust down- Wa'rdly to telescoping relation thereto. Three upstanding'pins '46 secured to the ring 44 at the sides and rear thereof project through holes '41 in the base spider 45' of the mandrel, with relatively generous clearance between said recesses 4 1 and the pins 46. The purpose of pins 46 is 'to guide the mandrel 45 in its forward to rear rocking movement while permitting some slight amount of lateral shifting on ring 44, as well as to hold the mandrel from upward separation from the base Ill. The mandrel is normally urged in the rearward direction by a coil spring 53 disposed in an upwardly opening recess 52 at the forward side of the supporting ring 44 (see Fig. 9).

It is evident that when the plunger 36 is elevated, the conical cam surface 31 thereof acts on the various mandrel sections 38 to urge the same uniformly outwardly in the radial direction to predetermined, expanded position. In this position the respective outer arcuate surfaces of the sections are disposed concentrically of the axis of the cam and also concentric with the split bell 22 in the closed position of the latter. They grip the inner periphery of the reinforcing ring.

The spider 45 of mandrel 45 is provided with an integral, upwardly extending,tubular extension 55 in which is received a supporting post-56 for the auxiliary mandrel member 51, to which said post is fixedly secured. The bore in the spider extension 55 is of suflicient diameter to freely receive the post, so as to enable the rocking movement of the mandrel referred to above. Post 56 extends downwardly through the bore of the tubular mandrel expanding plunger 36, as illustrated in Figs. 5, 7 and 9, and is adapted to be lifted upwardly to elevate the auxiliary mandrel member 5'! when it is desired to assemble containers of larger size and axial dimension. To this end, the post 56 is axially slotted at 58 to receive and be sustained by the transverse supporting pin 59 which extends across the bore of tubular spider extension 55. Slot. 58 has a lateral offset 58' which is engaged with pin 59 in an elevated position of auxiliary mandrel member 51, upon slight rotation of the latter. This affords simple means for selectively supporting the auxiliary mandrel member at diiferent vertical positions relative to the main expansible mandrel sections 38. Two different vertical positions of the auxiliary mandrel member 51 are. indicated in solid and dotted lines, respectively, in Fig. 1.

The movable assembling head l3 is also supported on the base H! of the apparatus for vertical adjustment in accordance with the vertical positioning of the auxiliary mandrel member 57. To this end, each of the tubular supporting posts 20 of base l0 slidably receives. a telescoped, vertically adjustable head supporting rod 60. Suit-.- able simple provisions, for example, a removable pin 60 extending through post 20 to fit in vertically spaced holes in the rod 60, may be employed to enable the head I3 to be supported at different elevations corresponding to the elevation of the mandrel member 51. c One or more holes 51' are drilled through'the skirt of auxiliary mandrel member 51 for the purpose of eliminating vacuum holding effect when the container is removed fromthe mandrel.

The. head I 3 includes a rigid backing plate 6| of substantial thickness provided with a pair of integral, laterally spaced and forwardly extending pivoting ears 62. These ears are pivoted to the upper end of the respective supporting rods 60 by means of the pin 63. The backing plate 6| is also provided with agripping'portion 64 adapted to be manually grasped by an operator in manipulatingthe head from the inoperative position illustrated in Figs. 1, 4', 5 and 6 downwardly and forwardly toward the position shown in dotted line in Fig. 9, and vice versa.

Dash pot cylinders 65 which are pivotally connected at one end thereof to the rear surface of the backing plate. 6| are :provided to cushion the return movement of the assembling head I3. The plungers 66 of these respective dash pot cylinders are each pivoted to a rearwardly extending arm 61 which is clamped on the adjacent adjustable head supporting rod 66. Coil springs 68 encircle said plungers and act to urge the same forwardly in the respective cylinders 65.

Head backing plate 6| carries'an integral bellhinging bracket 10 which projects forwardly therefrom, in the position of the head illus-,

trated in Fig. 4. A pivot pin 1| extending from.

plate 6| to a boss on said bracket plate, as illustrated in Figs. 4, 6 and 9 of the drawings, serves to hinge the respective semi-circular sections 12 of the split ring engaging bell M on head [3 to one another and to the backing plate. Sections 12 are similar to the base-carried bell sections 23 and, like the latter, each has an undercut ring receiving groove, designated 13. Sections 12 are urged to spread relation by suitable simple provisions corresponding to the coil spring 3|. They are adapted to be actuated to operative, closed relation to one another, so as to be circular and concentric with the axis of mandrel H in the final operating relationship of the various elements, which actuation takes place coincidentally with the expansion of the mandrel and contraction of hell 22, by the provisions illustrated particularly in Figs. 4 and 6.

These provisions include a pair of elongated links l4, 15, each of which is pivoted to one of the clamping sections 12, externally or the inner, shaped or inclined surface 13 of the latter, by means of a hinge screw 16 extending through the external flange 11 of said bell engaging section. Angularly disposed slots 58 in the head backing plate 6| receive said head pivoting screws 16 and permit inwardly-convergent. movement thereof as the links I4, 15 shift upwardly in a central vertical plane extending through the axis of the mandrel H and ring engaging bells l4 and 22. These links are articulated to one another by a pivot pin 85 which also pivots the links to a vertically slidable, elongated actuating member 8| of rigid, straplike character. Member 8| is slidably received in a suitable internal way in a cast external shield 82 secured to the rear surface of the head backing plate 6|. Said actuating member extends downwardly past the lower extremity of the backing plate (see Figs. 4, 6 and 9) and is turned forwardly at a right angle to provide a.

tappet element 83.

Immediately above the bell pivot pin the member 8| is shaped to provide a rearwardly extending latching nose 85, as illustrated in Fig. 6, through which'said member is adapted to be restrained in its upwardly thrust position, shown in solid line in Fig. 6, thereby maintaining the links 14, 15 inelevated position. The ring clamping bell sections 12 which are ac-.- tuated by said links are also held in closed, operative condition to clamp therebetween one of the rigid reinforcing rings which is to be applied to' the container being operated on.- A keeper dog- '86 is medially pivoted between a pair of ears 8! located on the rear surface of the head backing plate 6| and beneath a raised-por tion 82' of the shield 82,thisd0g being urged aces-ms a latching nose '89 adapted to engage beneath the nose 85 of the slidable actuating member 81-, as illustrated in Fig. :6. Ihe latching noses each have an inclined surface 90 adjoining the latching surface thereof whereby the member 8|, in sliding upwardly along the rear surface or the backing plate, is adapted .to cam the :dog 81 outwardly against the :force of spring 88, thereafter being engaged and latched by said dog.

In order to release dog 88 and enable actuatin member 8! to return downwardly to the inoperative position thereof illustrated in -dotted lines in Fig. :6,'-thereby enabling bell sections I2 to return to the spread-condition of Fig. 5, the dog has adjustably fixed thereon a forwardly extending release pin 9I which projects through an .aperture 92 in the backing plate 51. Thi pin '91 is so positioned that it engages the mandrel member 51 at the time that the head is fully swung forwardly and downwardly to its final assembling position, thereby shifting the pin 9I upwardly to disengage :the latch "noses 95, 89, whereupon the ring clamping bell sections I2 return outwardly to their inoperative, spread condition.

The mandrel assembly I I including the radially expansible mandrel segments 38, the tablemounted bell assembly '22 including the contractible sections 23 and the swing'able head-mounted bell assembly I4 including the contractible bell sections I2 are automatically actuated simultaneously by the following instrumentalities.

Referring particularly to Figs. 4, 5 and 8, the

table I8 is provided with a pair of depending brackets 95 of substantial mass and size which provide a f-ulcru'm for the L-shaped, main operating lever 96 on which the treadle or foot pedal I-i is rigidly secured externally of the skirt ill. The opposite arm of said operating lever extends rearwardly from the bracket and is pivotallyconnected by a pin 98 to a vertically acting, elongated actuating rod 99. This rod is provided with a plurality of longitudinally spaced holes I00 to enable the lever '96 to be selectively pivoted thereon, thereby adapting the head bell actuatin linkage to a condition in which the head I3 and auxiliary mandrel member 51 are in different vertically adjusted positions to operate on containers of different sizes.

The above described connection causes eleva tion of the actuating rod 99, when the treadle I8 is depressed, the rod engaging the ofiset tappet element 83 of the vertically slidable bell actuating member BI, which in turn actuates the ringsections 12 to operative, closed condition through links I4, I5. At the completion of this operation the member 8| engages the latching dog 86 to hold said sections in closed condition. 7

A further pair of laterally spaced depending brackets I02 on the table I8 serve as an auxiliary fulcrum for certain of the means which actuate the mandrel II and ring clamping bell 22 conjointly with actuation of bell I4. A straight link I 03 is medially pivoted at I08 to each of the brackets I02. The forward end of the respective links I03 is pivoted at I04, through a thickened spacer boss I03, to the lever 96; and the opposite, rear end of each of the respective links is pivoted at iii) I05 to the lower end of the cam sleeve 38. The

latter. is slotted at 36' to accommodate lever 55,, Accordingly, clockwise movement of the main,

lever 96 about its fulcrum 91, as'viewedfiin Fig. -4 produces downward-movement of the pivot point sleeve 30, although in a degree much less than the degree of movement of the main lever 96'.

Coincident with the foregoing operation, ';sec'-. tions .23 are urged toward one another through the agency ofza pair of bracket extensions I01, each rigidly welded to one of the links I03. Said bracket extensions are pivotally connected at their upper extremities to pull rods I08, which extend rearwardly and are coupled to the vertically depending pins :32 on the respective ring clamping vbellsections 23. Thus the latter are moved toward operative, contracted, :ring clar'np ing relation. This movement .is cushioned by a coil spring H19surrounding rod I 08, which spring is interposed between the abutment H0 on the pin 32 and an adjustable wing nut I'I-I threaded onto the free end or the pull rod I08.

In operation, a supply of the preformed container bodies, designated H5 in Fig. 2 of the drawings, the preformedlower and upper, metal reinforcing rings I I8, I I4 respectively, and the bottom closure disks II -'I are provided. The rings I18 have a radially extending flange or shoulder II9. At the commencement of the assembling cycle a reinforcing ring I I I is droppedabout man'- drel II and a ring H8 is deposited in the groove I3 of the open head bell section I2. A container body H5 is then preliminarily shaped by manually expanding the same towards its ultimate cyl-i'n drical outline. These bodies are fabricated in flat, knocked-down condition and can be expanded by simply applying compressive force to the opposite side margins of the collapsed article.

They are characterized 'by an integral, outwardly and downwardly ironed flange or bead H8 at either end thereof. The partially expanded container body H5 is slipped over the cylindrical mandrel member 5''! and pushed down by hand, approximately to the position illustrated in Fig. 9, adjacentthe reinforcing ring I previously de-' posited about the expansible mandrel section 38 and within the spread ring clamping bell sections 23. a container closure disk H1 is next placed over the top of the auxiliary mandrel member 51 within the walls of the body H5, whereupon the apparatus is ready to beo'perated.

The operator depresses the treadle I8 fully. whereupon the actuating plunger rod 99 is thrust upwardly into engagement with the tappet element '83 on the actuating member SI "for split head bell sections 12. This shifts the member up- Wardly and draws the sections to circular clamping position with their undercut groove I3 in external engagement with the reinforcing ring 'I I8 previously deposited therein. Simultaneously with this action, the table bell sections 23 are similarly contracted cooperative, closed condition to one another, through the agency of the brackets I01 secured to links IllII and the pull rods I08 operatively connected to the ring sections 23. The mandrel expanding cam sleeve 38 is also. thrust upwardly by reason of the clockwise pivoting of links I03 about their fulcrum I06, thereby camming the mandrel segments 38 outward to engage the inner surface of ring I I 4.

The mandrel II and clamping bell 22 may be retained in the respective operative conditions thereof byengaging the forward pedal extension of of lever 96 beneath the laterally stepped offset '21" of the treadle accommodating opening 2 I. This enables the operator to release his foot-. pressure on-thetreadl'e Ill. The head bell HI is held closed by the latch dog 86, as described above.

' scoped relation to the other flange H6 of said container body H5, with the radial shoulder H 9 of ring H8 in restraining end engagement with the end closure disk I I1.

During the final downward thrust of the head I3, the latch release pin 9| engages the mandrel member 51', through the interposed disk H1,

thereby releasing the latch dog 86 and allowing the head ring clamping sections 12 to expand outwardly to their normal, spread condition. The table ring clamping sections 23 are similarly released, and the mandrel segments 38 caused to return inward to inoperative position, by disengaging the lever extension 96' from the holding ofiset 2|. The assembled container is then lifted manually from the mandrel l I of the apparatus.

The above described apparatus is relatively simple and economical in its parts, and is capable of being operated rapidly and efiiciently by a single workman adequately supplied with a supply of preformed container parts. The reinforcing rings H4, H8 are unfailingly assembled in firm,

j displacement resisting relation to the container body H5, without damage to' the latter, and the time previously required for the assembly of comparable container structures by separate assembly operations performed at opposite ends of the container, is materially lessened by the present improvements.

I am aware that various modifications of the above structure are possible all falling within the principle of the invention. This concerns generally the combination of a pair of pivoted or relatively movable, split, contractible clamping bells or rings, one of which is associated with an expansible mandrel, preferably of an axially adjustable type, together with means for simultaneously contracting said rings and expanding said mandrel as a single, manually automatic operation, thereby placing the rings and mandrel in condition for a final manual operation to complete the intended container assembly.
